"My installer was very knowledgeable and professional. His team promptly installed the insulation and baffles, as I requested, and tried to clean up afterward. I was already sweeping the garage, so I declined. The cost was exactly as quoted. Would be nice if they made it an option to pay online. (Maybe thatâ s possible now.) There was an immediate improvement in the comfort in the home. I would highly recommend this company."

"I am extremely pleased with MILEX (MILO insulation). Work was done June 7 & 8, 2021. I have noticed a significant improvement in my home. Very professional, on time, worked nonstop except for a lunch break the first day (removing all old insulation- it was a MESS!). Worked nonstop the 2nd day - blowing in the insulation. I donâ  t hesitate to recommend to anyone and everyone"

Insulation FAQs, answered by experts

Yes, you can use too much bubble wrap. If you overdo it with the wrapping, it can strain the top of your box and break open the taped seal, risking the chance that the contents of the box could fall out or break. Use enough wrapping to fully cover your item without compromising the security of your box.

These two types of foams are similar chemically, but they are applied in a much different way and each has its own pros and cons. Spray foam can only be used if the area where you will be installing the installation is wide open and easy to access. Injection foam should be used where it's cost-prohibitive to remove the walls that are placed over the insulation. Spray foam is a much less expensive process and requires less expertise. 

No, you should avoid using antifreeze in your outdoor spigot to prevent freezing. Antifreeze can contaminate your water supply and harm the environment. Instead, employ safer and more effective methods for winterizing your spigot, such as draining the spigot and using insulation, to protect it from freezing temperatures.

It’s technically possible to install loose-fill cellulose insulation without a blower, but it’s much more time-consuming, tedious, and dangerous. You’ll need to wear the proper protective coverings to handle the cellulose after it’s been doused in boric acid; use a shovel when you can to transport the material from the bag into the wall cavity.

That said, if you purchase cellulose materials at a home improvement store, ask if they rent out blowers for free or at a discounted rate. In many cases, if you buy the material from the store, they’ll rent out the blower at no extra cost.

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.
